TO ALL WHOM I'.l. MAY CONGERN Be it known that I, ABIJAH TAYLOR, of Indianapolis, county' of Marion, State 'of Indiana., have invented certain mechanism for Propelling Vehicles; and I do hereby declare the following to be a full, clear, and exact Adescription of the same. I i

My invention consists of certain mechanism, 'fully-described hereafter, to be applied to vehicles for propelling the same without the aid of the usual wheels and axles.

In order to enable others familiar with machinery of this class to make and apply to practice my invention, I will now proceed to describe its construction and operation, reference being had to thevaccompanying drawing which forms a part of this specication, and in which, in drawing N o. 1 4

Figures V1 and 2 are side views'of the opposite end of my improved mechanism for propelling vehicles.

Figure 3, `an inverted plan view. i

Figure 4, a vertical s ction on the line I-Z, iig. 3 and V Figure 5, drawing No. 2, a transverse section of the mechanism, showing its application to a street cnryand Figure 6 a transverse vertical section on the line 3-4, ig. 1.

Similar letters refer to similarparts throughout the several views. l

The permanent portion of the device consists of along beam, composed of two ways or rails, A and A', secured one to each side of a central hollow g-irder, B, of metal, open at the top, as best observed on reference to iig. 5, drawing No. 2. At one end of ythis long beam, and in the opposite rails A'and A ynf the same, turns a shaft, C, which iscranked in the peculiar manner illustrated in figs. 1 and, for the purpose described hereafter. 0n this shaft are secured two whecls'"D`D, at a suitable distance apart from each other, each wheel having teeth adapted to the linksof-an endless chain, E, the two chains passing beneath the beam, partly round the two wheels and above the beam, and round two wheels F F,sit,uated a't the opposite end of the Beam, fig. 2, each ofthe latter wheels being securedto a separate spindle, and the two spindles turning in adjustable pieces E', secured to the rails A` A't suitable intervals, pendulous legs G, having feet g, are connected to the endless chains in the followiifgmanner: Each leg is hun'gloosely to a spindle, H, between two pulleys I I,'on the said spindle, which pulleys coincide with andjbear against the rails A and A', iigs. 1, 4, and 5. The tubular portion of the leg G, through which the spindle H passes, is' embraced by yokes J J, each yoke being connected to and forming a part of each endless chain E, as shown in g. 4'. 1 Power is applied to the shaft C, so as to turnV the wheels D D, which we will suppose to be revolving in the direction of the arrows, fig. 1.'. The foot ci' .the leg Gis resting on the ground, and serving with other feetto support the entire beam and its appurtenances, the beam resting on and gliding over the pulleys I, the-spindle of which is supported by the leg. As' the chains traverse the course indicated, the entire mechanism will of course traverse in the direction of the arrow fig. 1, and when the portionof the chains towhich the leg is connected `passes round the wheels D D, the foot will be elevated from the ground, carried round with the chain, Vthe cranking of the shaft c permitting the leg to pass freely between the wheels, and will finally occupy`the pendulous position shown in iig. 5, and by dotted lines in iig. 1, within the channel formed by th'ehollow girder B, the wheels I I bearing on the`upper surface ofthe rails A A. Along this channel the leg traverses untilitreaches the opposite end of the beam, where, by the passage ofthe chains round the pulleys F F, the leg is lowered until its foot is in contact with the ground, and is in a position as beforeto support, in combination with other legs, the main beam and its attachments. It will he understood that the feet are arranged at such intervals that 'there are never less than two feet at one time beneath the beam. c

One application of 'my invention is illustrated in tig. 5, where the red lines representa section ofthe lower portion of a street car, to which the rails A and A are secured, the seats 'an of the car serving to cover the mechanism described above. When the propelling apparatus vis .thus'situated midway between theopposite sides ofthe car the latter may be steadied bywheels g g, shown byred lines, or propelling mechanism similar to that' Vdescribed may besituated near each sidaofthe car, in which case no steadying wheels will be required .It will be evident that lthe propelling device `may he applied in different ways; the endless chain, for instance,

with its pendulous legs, in ay pass entirely over, the car or'other vehicle, to which therails are secured. An 'endless wire rope or steel band may besubstituted for the chain. No matter how or to what vehicles the i i i Y i mechanism may be' applied, it will be evident that as .there is -no dragging of the legs on'the ground, and as the pulleys I I serve as anti-friction wheels the propelling mechanism is free from that wear and tear and undue friction to which ordinary wheels and axles are subjected. The rails A Aimay be so curved that there may be a place and' time where and when the entire machine may have but one bearing for the purpose of easily guiding and turning the car. Y I

It .Willbe evident that the mechanism described above may be altered and modified without departing from the main features of myinvention; for instance, a single chain, with legs secured directly to instead of hanging loosely on the same, may b used in place oi'two chains. Without .confining myself, therefore, to the'precise con struction and arrangement of parts herein described, I claim as my invention, and desire to secure by Letters Patenty Propelling. mechanism, consisting of' an endless chain or chains, bands or ropes E, nays or rails A A', anti-friction pulleys I I, and legs G with feet, the said legs being carriedby the chains, 'ba-nds, or ropes, and the whole being arranged and operating substantially as and for the purpose herein set forth forth.

In testimony whereof I'have'signed my name to this specification in the'presence of two subscribing witnesses.

' ABIJAH TAYLOR.
